CLOSURE FOR PoW'E'R VDEVICES.

Application fijed June 2, 1925. 'Serial ivo'. 34,383.

' This invention relates to a'closure for a power device embodying agearing and has been especially designed for use in connection with thetransom operating mechanism disclosed in my copending'applicat-ion,Serial'No.34=,384.

An important object of the invention is to provide a closure "orhousingfor- 'a manually operated worm gearing'and its rotatablespindles.

A further object lies in the provision of means for concealing the Ywedge connection between the spindle 'of said 'worm' gearing and acrank: I .L

A still further object resides in 'thec'onstru'ction of a spring pressedclosure which may be retracted to-expose certain connecting parts duringthe asseinbling'or disassembling of the mechanism contained in thehousing. I

Another object is to provide a housing of this character'whichwlllbesimple and in expensive to manufacture, admit of ease and economy in,assembling together with several parts of mechanism. f

My invention consists in various novel constructions and combinations ofparts, all as hereinafter described and'particularly pointed outjin theappended claims; and will be readily understood by reference to theaccompanying drawings, which form part of this specification.

Insaid drawings:

Figure 1 is, a front elevation of a housing.

Fig. 2 is a side elevation of a housing and its component parts, or morespecifically, as it appears when connected to a transom operatingmechanism.

Fig. 3 is a horizontal sectional view taken through the major axis ofsaid housing, substantially on the line 3-3 of Fig. 1; and

Fig. 4 is a vertical sectional view of the housing on the line 44 ofFig. 1, the component parts of the mechanism being shown in the positionindicated in Fig. 2.

As hereinbefore pointed out, I have designed this housing with specialreference to a transom operating mechanism, such as find common use indwellings, oflice-buildings and hotels. where a neat and compact deviceis favorably received. Its limitations. of course. are not to berestricted to this use s lely, is obviously my invention will be foundextremely useful in the large field of mechanics where n a simple andinexpensive meanfs'for inclosing a gearing is required.

" On inspection of the drawings it will be 5 shown-in Fig.3. 'Therea-r'of thew-housing is left openfor the insertion of the gearing as will bemore specifically pointed out hereinaftefQ-T A v As shown in'Fig. 1"thehousing'5 is provided with an upstanding extension 9, which is'fa'prt'ured, as indicated at l0,for the rec'eption of a rotatable shaftofia"tran'so'm operating device. This'extensi'on is rounded over infront, blending intothe face'and flange of the body portion to present aneat and artistic'appearance, while the sides and top thereof'continuestraight to the rear.

Arranged eccentrically with the minor axis of the housing is a.forwardly directed annular flange 11, having a centrally aperturedpartition 12 at the base thereof, said partition being substantially ona plane with thcface 6. The aperture in the partition 12 is designatedby the numeral 13, and disposedradially thereof are smaller apertures 14and 15, preferably positioned as indicated in Fig. 1. I

In assembling the various parts, the gearing inclosed in a specialcasing 16, is inserted by the rear of the housing and the hub extension17 containing and furnishing a bearing for the spindle 18. enters theaper ture 13, and is centrally positioned therein by inserting the pins19 and 20, of said casing 16. into the apertures 14 and 15 respectively.As clearly illustrated in Fig. 1- the casing 16 bears against the rearface of the partition 12 while the vertical spindle 21 is alined withthe aperture 10 and in position for connection with the shaft of thetransom operating device.

I now direct particular attention to a novel closure means which I haveadopted for clos- ,ing the space within the annular flange 11, and asthis feature is perhaps more clearly shown in Fig. 4, the balance of thedescription may be read on same.

The numeral 2?. denotes a closure, formed illustrated. its rear beingslightly en.

inwardly to form a bearing portion 23, which operates within the flange11, while its front end is. reducedain. diameter and bent upon itself,as indicated at 24.

The gearing casinglG being now positioned Within the housing 5, theclosure 22 is next placed within the space within the annular flange 11,and is depressedcto pracV-V tically contact with the partition 12' toexpose alined apertures 25 and -26rin;thecrank 27 and spindle 28. Awedge pin 29 is then inserted in: said apertures. '25 wa d-26 firmlyconnecting thecrank and spindle 28.
